The RS-10 loudspeaker uses a BMR (Balance Mode Radiator) to handle the majority of theaudible music spectrum.

The BMR design concept was conceived as a full range driverhandling all musical frequencies from bass through to treblewith a single driver and no crossover.

This concept worksremarkably well and produces a musical transparencynormally associated with electrostatic loudspeakers.

However no concept is perfect and a single BMR can onlyproduce limited bass output and some people may prefermore precise musical images.

Most loudspeaker systemshave a crossover point for the midrange driver and tweeterbetween 2 KHz and 3 KHz. This can upset the vocal regionwith distortion and phase shift. It is also where the human ear is most sensitive.

Therefore with use of the BMR unit, Rega has been able to design a crossover pointabove the most critical range.

The high frequency capability of the BMR, has allowed thetwo units to integrate to 6 KHz. This gives massive improvements in sound quality withgreater clarity and detail in the music. Rega has pioneered the integration of a BMR withthe unique Rega dual driver bass system and a completely new and unique Regadesigned and UK manufactured tweeter.

The high frequency sound of a BMR is so good that the quality level of any normaltweeter will not combine with it. This is why Rega felt compelled to design a new andunique tweeter that would complement the BMR unit.

Each tweeter is meticulously hand assembled atRega’s factory in the UK and incorporates a copper Faraday ring whichextends the frequency response of the tweeter up to 23Khz by loweringinductance of the voice coil.

For bass frequencies the RS-10 uses two separate bass drivers connected in parallel.

The drivers are different sizes, have different resonant frequencies and operate withindividually separate cabinet loading: A 200mm driver with alightweight paper cone, 8 layer voice coil and a resonantfrequency of 40Hz operates in a transmission line with portoutput extending below audibility coupled with a 125mm driveralso with a lightweight paper cone, 8 layer voice coil andresonant frequency of 75Hz which is loaded by a smallsealed cabinet.

This system eliminates the normal single bassresonance byspreading smallerresonances across the entire bass frequencyband and incorporates a degree of self dampingdue to the parallel connection with theamplifier.

The result is a much tighter and moretuneful bass register which can be adjusted inlevel to suit room characteristics.

Theloudspeaker can also be moved closer to orfurther from a wall resulting in an increase ordecrease of low frequency to suit personalpreference.
